Have you ever needed to create a .npmrc file or another file or folder that starts with a dot and hit an issue when you tried it in Windows Explorer?
If you've tried it, you will see this infuriating error in Windows Exlporer
You must type a file name.;
You've probably given up at that point and resorted to doing it through the command line.
Well there's an easy way round it, add a dot at the end, so
.npmrc.. Windows Explorer then automatically removes the dot at the end and you are good to go.
Simple when you know how!
